I am trying to enable OTA partitions in ESP32-C3 by changing the custom partition file in sdkconfig file.
But it's not getting enabled. Can you please help?

OTA in esp32-c3

closedby robbietree8opened 2022-05-12updated 2022-05-13

hello,

It seems the port to esp32-c3 does not support OTA, but I found there is GENERIC_OTA port, the difference between them is mpconfigboard.cmake file, so I tried to add line boards/GENERIC_OTA/sdkconfig.board to mpconfigboard.cmake file in GENERIC_C3, and builds the firmware locally.

Unfortunately, when I implemented OTA via bluetooth, the partition of ota_1 is updated successfully, but it does not boot ok, following error occurs:

E (68) esp_image: Segment 0 0x3fcd6100-0x3fcd6fa0 invalid: overlaps bootloader stack
E (69) boot: OTA app partition slot 1 is not bootable

Demo project can be found in micropython-ota-example

Appreciate if anyone can take a look.

Both issues describe the same problem: OTA partitions not functioning on ESP32-C3. Issue #8659 (candidate) is older and more detailed — it identifies that GENERIC_C3 lacks OTA support compared to GENERIC_OTA, provides a specific bootloader stack overlap error, and links a demo project. Issue #12703 (query) is newer and vague, describing what appears to be the same root cause (OTA partition configuration on ESP32-C3 not working) without specific error output. The candidate does not appear to have been resolved, so this is not a closed/fixed duplicate — both issues remain open on the same underlying gap.

Suggested action

Close #12703 as a duplicate of #8659. The older issue (#8659) has substantially better diagnostic detail, a concrete error signature, and an example project. Direct the reporter of #12703 to follow up there with any additional reproduction details.
